Need a ID on creature

[jonfr]

Can somebody help me ID this create, I have no idea what it is. It has a other, but smaller under it. As can be seen on the picture. It problay did hike a ride with a live rock that I did get from the coastline where I live.

I'd ask the folks in the Mantis Shrimp forum above about this one.

 

[jonfr]

Is it a shrimp ? I am not sure on that.

 

[Grins]

Probably not. Looks more like a giant pod but I'm stumped. Maybe something that we don't see here in the states?

 

[jonfr]

It did come from the local coastline. That is for sure. As I haven't bought any live rock yet. I am just using live rock from the coastline at the moment.

If you don't get an answer here you might try taking the photo into your local fish store.

 

[jonfr]

I don't have any local fish store.

It might be possible that this is a Gammarus species, this is just a guess, I still have no clue what it is. But I have few Gammarus fossarum shrimps (or species closley related to it) in my tank.

Most certaintly not a mantis. No eyes, no enlarged raptorial appendage, The carapace and telson aren't separated like a mantis. But I am also interested in this. It looks like a colorful land bug.

It's flattened from top to bottom, which would make it an isopod.

This isn't a land bug, this creature has gills far as I can tell. But greenbean36191 is right on the group of species. What exact species this is I don't know.

It's an isopod in the family Idoteidae. These are primarily herbivores and many of them have the same color as their food source.

You'll find images of marine inverts from the scandinavian areas - which overlap with the icelandic fauna - at http://www.marinbi.com/

There's a paper on coastal animals off Surtsey, Iceland which lists intertidal animals including some Idotea species at - http://www.surtsey.is/SRS_publ/2000-XI/2000_XII_3_04.pdf

Thanks for the ID, the smaller one did die last night. I am unsure why. But I have just finised setting up my tank, so this is not a surprise that it did die. The larger one however is still alive and appears to be doing good at the moment.
